The code has something to do with the fuel system. I put on a new gas cap and had the light reset, but still have the problem. Any ideas?

That is the system that monitors and captures fuel vapors from the tank. That specific code is generic and there will likely be a more specific factory code stored there also but it may take a professional scan tool to access it. It will definitely take one to diagnose it along with a smoke machine. This code will have absolutely no effect on the way the vehicle runs. It's emissions only ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
